ribosomal RNA (rRNA)

Ribosomal RNA (rRNA) is a fundamental component of ribosomes, the cell structures responsible for protein production. It combines with proteins to form the structure of the ribosome, enabling it to read genetic instructions from messenger RNA (mRNA) and assemble amino acids into proteins. rRNA plays a crucial role in catalyzing this process and maintaining the ribosome's structure. It is highly conserved across different organisms, reflecting its essential function in all living cells. In essence, rRNA acts as both a blueprint and an active participant in building the proteins vital for life.
